Koch-Chemie Paint Correction: German Compounds, Polishes & Pads for Swirl Removal

Remove swirl marks, scratches, and oxidation with Koch-Chemie's professional-grade paint correction system. This collection includes everything you need — from the aggressive H9.02 Heavy Cut cutting compound to jeweling-grade finishing polishes like M3.02 Micro Cut, plus the matching foam pads engineered to work with each formula. These are the same German-made compounds used by professional detailers and body shops worldwide.

What sets Koch-Chemie apart is the system: every compound has a numbered cut level and a color-matched pad, so building a cut-and-finish combo is simple instead of guesswork. Load your DA or rotary polisher, wipe down with panel prep, and lock in the gloss with a ceramic coating or product from the Koch-Chemie protection line.

What Is the Koch-Chemie Polishing System?

Koch-Chemie uses a simple numbering system: the higher the number, the more cut. H9.02 (cut level 9) is the most aggressive, F6.01 (cut level 6) handles medium correction, and M3.02 (cut level 3) is a fine finishing polish. Every formula is silicone-oil-free and built on a homogeneous abrasive grain, which means predictable cut levels, low dusting, and a long working time that won't dry out mid-panel. That consistency is why the line performs on both soft paints and hard, scratch-resistant clear coats — and why body shops trust it for pre-coating prep.

Koch-Chemie Compounds & Polishes by Cut Level

  • H9.02 Heavy Cut: The most aggressive cutting compound in the line — for deep scratches, sanding marks (1200+ grit), and heavy oxidation. Test on a small area first; it's a serious compound.
  • F6.01 Fine Cut: Medium-cut polish for moderate defects — general swirls, wash marring, and one-step correction on softer paints. The most versatile compound for everyday correction work.
  • P6.02 One Cut & Finish: A true one-step polish with good cut and strong finishing ability — correct and gloss in a single pass on daily drivers.
  • P3.01 Micro Cut & Finish: Light cut with excellent finishing — ideal for newer paint or final refinement after a heavier step.
  • M3.02 Micro Cut: Ultra-fine finishing polish for maximum gloss and hologram removal — the jeweling step that makes dark paint look wet.
  • P1.03 Lack-Polish Grün: All-in-one hand or machine polish that cleans, polishes, and protects in one product — the easy button for enthusiasts without a full pad arsenal.

Match the Pad to the Compound

Each Koch-Chemie compound has a foam pad engineered for it — matching them gets you the cut and finish the formula was designed to deliver:

  • Heavy Cut Pad: Firm foam for aggressive correction with H9.02.
  • Fine Cut Pad: Medium-density foam for balanced cut and finish with F6.01.
  • One Cut Pad: Versatile foam for one-step polishing with P6.02.
  • Micro Cut Pad: Soft finishing foam for the final polish with M3.02 or P3.01.
  • Polish & Sealing Pad: Ultra-soft foam for sealant application and jeweling.

One-Step vs. Multi-Step Paint Correction

A one-step correction uses a single polish-and-pad combo — P6.02 One Cut & Finish or F6.01 — to remove light-to-moderate swirls and boost gloss in one pass, the fastest route to a big improvement on daily drivers and softer paints. A multi-step correction (cut, refine, finish) removes heavier defects on hard clear coats: start with H9.02, refine with F6.01, and jewel with M3.02. Either way, start with the least aggressive combo that gets results — and never skip the finishing step after compounding, since that's what removes the haze compounding leaves behind.

Quick Guide: Match Compound & Pad to the Defect

Deep scratches, sanding marks, heavy oxidation H9.02 Heavy Cut + Heavy Cut Pad Cut level 9 removes 1200+ grit sanding marks and severe defects
Moderate swirls & light scratches F6.01 Fine Cut + Fine Cut Pad Medium cut level 6 balances defect removal with a clean finish
One-step correction on a daily driver P6.02 One Cut & Finish + One Cut Pad Good cut and finishing ability in a single pass
Minor swirls or newer paint P3.01 Micro Cut & Finish + Micro Cut Pad Light cut with excellent finishing on fresh or delicate paint
Holograms & maximum final gloss M3.02 Micro Cut + Micro Cut Pad Ultra-fine abrasives erase buffer trails and jewel the clear coat
Polish by hand, no machine P1.03 Lack-Polish Grün All-in-one formula cleans, polishes, and protects — hand or machine
Apply sealant after correction Polish & Sealing Pad Ultra-soft foam spreads sealants evenly without marring fresh paint

How to Do Paint Correction with Koch-Chemie (Step-by-Step)

  1. Wash and decontaminate first. Correct paint must be clean paint — do a thorough wash, then remove bonded contamination with Koch-Chemie decon & prep products or a clay bar. Polishing over grit just grinds it into the clear coat.
  2. Inspect under good light and test a spot. Gauge the defect level, then start with the least aggressive combo that gets results — often F6.01 on a Fine Cut Pad. Step up to H9.02 only if the test spot demands it.
  3. Cut in small sections. Work roughly 2 ft × 2 ft areas with slow, overlapping passes. Koch-Chemie's long working time means the compound won't dry out mid-panel, so let the abrasives break down fully before wiping.
  4. Refine and finish. Follow any heavy cut with a finer step — P3.01 or M3.02 on the Micro Cut Pad — to remove compounding haze and maximize gloss.
  5. Wipe down with panel prep. Polishing oils can hide leftover defects and block coating adhesion. A wipe with Panel Prep Spray shows you the true finish and leaves bare paint ready for protection.
  6. Protect the finish. Fresh clear coat is unprotected — seal your work with a wax or sealant, a ceramic coating, or the Koch-Chemie protection line.

Koch-Chemie Paint Correction FAQ

What's the difference between H9.02, F6.01, and M3.02?

H9.02 is the most aggressive (cut level 9) for heavy defects and sanding marks. F6.01 is medium (cut level 6) for moderate swirls and one-step work. M3.02 is a fine finishing polish (cut level 3) for removing haze and maximizing gloss. Most corrections use 2-3 steps: cut, refine, finish.

Can I do a one-step paint correction?

Yes. P6.02 One Cut & Finish or F6.01 Fine Cut can often achieve excellent results in one step on newer vehicles or softer paints — typically removing the majority of visible swirls. For harder clear coats or heavy defects, a multi-step correction produces better results.

Are Koch-Chemie compounds silicone-free?

Yes — all Koch-Chemie polishing compounds are silicone-oil-free. They're safe for body shop use and won't interfere with ceramic coating adhesion, which is why coating installers prep with this system.

Do I need a DA or rotary polisher for these compounds?

Both work. Dual-action (DA) polishers are more forgiving for beginners; rotary polishers cut faster but require more experience. Koch-Chemie compounds are formulated to perform with either machine type — browse polishers & buffers to find your match.

What size pad should I use?

Match your pad size to your polisher's backing plate. Koch-Chemie pads are available in 2", 3", 5", and 6" sizes. Smaller pads are better for tight areas and curved panels; larger pads cover big flat surfaces more efficiently.

What do I do after polishing?

Wipe the panel with Panel Prep Spray to remove polishing oils, then apply protection — a sealant or wax or a ceramic coating — to lock in the corrected finish.
